2008 Annual Report on Uranium Management Activities

In 2009, the CNSC and Environment Canada released the first joint annual report entitled Risk Management of Uranium Releases from Uranium Mines and Mills - 2007 Annual Report. It focused on uranium releases to the environment from three uranium mining and milling facilities: the Rabbit Lake, Key Lake and Cluff Lake Operations.

The scope of the 2008 Annual Report on Uranium Management Activities (PDF) was expanded. In addition to documenting uranium treated effluent releases from the previously specified uranium mines and mills still operating, reporting includes all uranium mines and mills, as well as other CNSC regulated facilities releasing uranium in treated effluents.

Highlights of the 2008 Annual Report include the following:  

  • The uranium mining sector was once again the best performing mining sector relative to the Metal Mining Effluent Regulations effluent limits, with no exceedances in 2008.
  • Uranium in effluent from CNSC licensed facilities did not result in significant risk to the environment in 2008.
  • The CNSC is being proactive in pollution prevention by introducing a screening objective for uranium in effluent that is much lower than the most stringent existing requirements.
  • The CNSC is being proactive in pollution prevention by introducing a screening objective of 0.1 mg/L for uranium in effluent. This concentration of uranium in effluent is achievable with present day standard treatment technology. The CNSC will be consulting on a policy discussion paper on this broad in the near future.
  • The CNSC is developing a procedure to establish effluent limits, incorporating the principles of pollution prevention, and those of ALARA and Best Available Technologies and Techniques.
  • The CNSC and Environment Canada are meeting their regulatory commitments and responsibilities associated with the safe regulation and risk management of uranium releases from nuclear facilities.
